FLUSH'ING APPARATUS.

Appli-cation filed October 12, 1926. Serial No. 141,218.

This invention has reference to an improved flushing apparatus for waterclosets, bidets, shower baths and similar apparatus, the object of theinvention being to provide an apparatus in which the discharge of waterfrom the tank is controllable at will, trom the smallest amount to acontinuous discharge.

The invention consists essentially of a completely closed tank, intowhich water is delivered through a tube provided at its end with avalve, the tank being also'provided with an outlet pipe equipped with avalve. These two valves are mounted on a single carrier for movement inunison and are operated by the same lever. rIhe inlet valve is normallyin a slightly opened position and the outlet valve closed. Operating thelever the outlet valve can be opened at the same time that the inletvalve is opened wider; during this operation water is dischargedt-hrough the outlet pipe under pressure due to the accumulation orn airin the top portion orn the tank, the pressure of which corresponds tothe pressure in the water supply pipe` .By keeping these valves openedat'ter the forced discharge of water has beengproduced, a continuousstream of water is obtained as long as required.

In order that this invention may be thoroughly understood Aand easilycarried intoY effect, it has been illustrated in one of its preferredforms ot construction in the accompanying drawings, in which:

Figure 1 is a vert-ical section ot the apparatus.

Figure 2 is a plan view of the adjusting` sleeve.

Figure 3 is a side view ot the apparatus, and

Figure 4 is a plan view of the same.

In all the figures, the same numerals indi cate similar or correspondingparts.

The apparatus includes a tank 1, of more or less rectangular section andhaving a cone shaped bottom. On the top wall ot the tank is screwed acover 2 which is provided with an internal passage to which the watersupply pipe 3'is connected and which has a cap scr-ew rIhe tank has twollugs 5 which serve to hang it in the desired position.

An adjusting sleeve 6 is screwed in theA bottom of the tank and islocked in position by a nut 7, and to the end of said sleeve theconnection 8 of the outlet pipe is screwed.

The internal passage in the cover 2 also communicates with a verticaltube 9 attached to said cover and which has at its lower end a sleeve-10 vcontaining within it a. valve 11, between which valve and thebottoms of the sleeve a rubber washer 12 is interposed that constitutesa seat for said valve when the latter is fully closed. i i

This sleeve is followed by another sleeve 13 provided with lateralperforations for the passage of water into the tank. The said valve 11is mounted on a rod 14- which eX- tends through tube 9 and projectsdownwards carrying two washers 15, 16 held to it by pins 25. Betweenwasher 15 and sleeve 13 a thick rubber washer 17 is placed which acts asa spring and'between the two washers 15, 16 there is a rubber piece 18which forms the outlet valve and rests on the seat formed by the topportion of the adjusting sleeve 6.

The upper end ot the rod 14 projects through the cover 2 and through thepacking 21 contained in a stung box formed by the interi'itting parts 19and 20; the part 19 being screwed into the cover and having screwed onit an outer sleeve 22, the upper edge of which has the form ot a screwor cam. A complemental part 23, whose lower edge also has the form ot' ascrew or cam, rests on sleeve 22, as shown, this part 23 constitutingthe hub of the operating handle. The top end of the rod 14projectsthrough this hub and carries a retaining button 24 fastened toit by a pin 25.

The adjusting sleeve 6 has for its object screwing it in or out willcause said valves, due to their being fastened to the same rod 14, toopen more or less. Said adjusting sleeve should be turned the extentnecessary for the inlet valve 11 to be suciently separated from its seattor allow the tank to be filled in a convenient length ot time. Theopening of this valve 11 will, therefore, depend on the size of thewater feed pipe and to adjust the closing of the valves, since on thepressure of the incoming water. A Y

plug 26 is screwed into the top wall of the tank to release the pressurewithin the tank when necessary. y

To operate the apparatus, it is merely necessary to turn the handle 23which, by means orp its cam hub, will cause an upward movement of rod 14and, with it, the outlet valve 18, thus compressing thespring or cushion17. The compressed air in the top portion ot the tank thereupon Jforcesthe escapes into the tank through the perfora" pipe. At the saine time,the inlet valve 11 is raised further away fromits seat, so that the v Yvolume'of water normally contained in the tank and then being dischargedis increased by the water that iiows through pipes 3 and 9 and, passingthrough the sleeves 10 and 13,

tions in the latter sleeve. Consequently, the initial .violent or forceddischarge of water is always succeeded by the discharge of a continuousstream of water so long as valve 18 `remains open.

As soon as the handle is released, cushion 17 expands, thereby loweringrod 14 and closing valve 1S, while the inlet valve 11 returns to itsnormal position, leaving suiiicient opening for the incoming water torefill the tank until the air pressure in the tank balances the pressureof the water and the inflow ceases. It is to be understood that valve18, being made of rubber, will yield slightly underV the pressure of thewater in the tank and will produce, as a. result, a slight downwardmovement of rod 14 and valve 11, so that the latter may, at a certainwater level,

seatagainst washer 12 depending, of course, upon the normal position ofsaid valve with relation to the washer. This normal position isregulated by the adjustment of sleeve 6 whei'eon valve 18 rests; andbecause of-that fact, such adjustment will `vary the time required foriilling the ta-nk, as will be understood.

Y lt is evident that the invention can embody forms, proportions anddetails' of construction other than those herein illustrated and -watertank provided at its bottom with an outlet; a water inlet tube mountedyin the tank inline with 'said outlet and'provided at its lower end witha laterally-perforated sleeve to enable the passage of water throughsaid tube into theV tank; avalve rod passing through said sleevek andtube and project-ing `at its upper portion through the top of the tank;an inlet valve and an outlet valve fixed one above the other to said rodfor movement in unison therewith, the inlet valve being disposed withinsaid sleeve for coaction with'a valve seat therein abovethepei'forations to controlthe outflow of water through Vsaidperfoi'ations, and the outlet valve acting to open and close thetankoutlet; and an operatin'gmember attached to the projecting por# tionof the valve rod to raise or lower the same. ,j

2. Flushing apparatus, comprising a closed water tank provided at itsbottom with an` outlet; a water inlet' tube mounted in the tank inlinewith said outlet and provided at its lower end with alaterally-perforated sleeve to enable the passage of water through saidtube into the tank; a valve rod passing through said sleeve and tube andprojecting at its upper portion through the top of the tank; an inletvalve and an outlet valve iiXed one above the other to said rod formovement in unison therewith, the inlet valve being disposed within saidsleeve for coaction with a valve seat therein above the perfor-ations tocontrol the outflow of water through said perforations, and the outletvalve acting to open and close the tank outlet; an operating memberattached to the projecting portion of the valve rod to raise or lowerthe same; and a spring cushionmounted on said rod Lbetween Vthe bottomof the sleeve and the outlet valve and acting normally to force the roddownward. Y Y

8. Flushing apparatus, comprising a closed kwater tank;aii adjustingsleeve mounted for projecting at oposite ends into `the adjusting isleeve andthrough the top of the tank; a water'outlet pipe in threadedconnection with said adjusting sleeve to permit the vertical movement ofthe latter with relation to the former and to the tank bottom; an inletvalve and an outlet valve fixed one above the other to the valve rod formovement in unison therewith, the inlet valve being disposed within theperforated sleeve forV coaction with a valve seattherein above theperforations to control the outflow of water therethrough, andV theoutlet valve being adapted to seat upon the upper face of the adjustingsleeve; a spring interposed between the bottom of the-apertured sleeveand the outlet valve to force said outlet valve and the valveV roddownward so as to hold4 the outlet valve against itsseat, whereby thevertical movement of the adjusting sleeve will raise or lower the valverod and its valves; and eX- ternal means for raising or lowering saidrod independently ofthe movement effected by the adjusting sleeve'.
